Ordered, collective motions commonly arise spontaneously in systems of many interacting,
active units, ranging from cellular tissues and bacterial colonies to self-propelled colloids …

The collective dynamics of active biopolymers is crucial for many processes in life, such as
cellular motility, intracellular transport, and division. Recent experiments revealed …

An active chiral rotor is a spherical object that can generate chiral flows in a fluid by rotating
about an axis. For example, if the flow around the upper hemisphere of the chiral rotor is in a …
